im currently gonna run a jspec t2 s5 motor , my question is im gonna be using the s4 t2 afm and boost sensor and removing all emissions equipment on the motor itself . can this be done by using the s4 t2 ecu ? if someone can give me a link to the info i need i would greatly appreciate it. thanks

 

yes, u will need to use s4 injectors, b/c s5 is high impedance and s4 is low.
but u can use intake manifolds and turbo
um..u might need to change the front cover .. i dont' remember someone correct me if i'm wrong
go onto www.teamfc3s.org/forum and search i think that site is alot easier

 

There's 2 ways:

Here's one, I'm in the process of doing it right now.....

i currently just got finished doing this swap. here are some useful links

rotary resurrection is the best place for this info i also refer with hailers he is one of the most knoledgeable (cant spell) on this forum. i used the na s4 harness removed the rats nest blocked off all emmisions and am premixing so i blocked off he omp. to do this u need to run 1oz per gallon correct me if im wrong but that will give you 128;1 ratio.
i currently still am running the na ecu due to the fact that i havent been able to find the n333 n332 that i am in need of. also i disconnected the tps cause it was causing an idle problem. also the afm and boost pressure sensor are off the original na motor.
the problem i am running into now is the driveshaft is not matching up with the jspec trans to the na rear. so you will need to get the custom made bracket for it change the rest of the driveline or get the t2 yoke welded onto the na driveshaft. or use the na trans just change the flywheel. but you still need the the counter weight if it is a s5 t2 keep s4 to s4 and s5 to s5. but without emmissions (cant spell again) and the rats nest it should be a peice of cake. keep an eye out for an update tread on my newest fc project soon to be posted.
if i offended anyone or stated somethin diferent im just going by what i have resurched and came up with so far

 

mazdatrix sells the DS you need....doing this swap now, but using the S5 T2 engine harness and the S4 NA body harness...little electrical swaps, but not too bad....need both pinouts for both harnesses...learning wire colors makes is a 1000X easier

 

i was gonna do it that way to but ten i got a lil deeper into the harness and come to find out they cut it but retaped it to look like it wasnt . hahaha , great joke right. but she runs now. i know there are kits and shafts out there but i just cut and welded it wrked fine for me but thats probly cause on military post i have access to all the equipment i preetty much need (well most of the time anyway) thanks though. but gl with your swap and if you find the wire tech and all for that id really like a copy for my records just in case someone or i need it later. thanks
